Eye Health and Assistive Devices

Myopia, also known as nearsightedness, is a common eye condition where distant objects appear blurry while nearby objects are clear.

Eyeglasses and contact lenses are primarily used to correct refractive errors such as nearsightedness, farsightedness, and astigmatism, enabling clear vision.

Magnifying glasses are commonly used by individuals with low vision to enlarge text and images, making them easier to see.

An eye chart is used during an eye exam to measure visual acuity, which is the sharpness or clarity of vision.

Cataract is an eye condition where the lens becomes cloudy, resulting in blurred vision, glare, and difficulty seeing in dim light.

For adults without any eye problems, it is generally recommended to have routine eye exams every 2 years to detect any potential issues early.

Screen readers are assistive devices that read aloud the text displayed on a computer screen, enabling individuals with low vision to access digital content.

Cataract is the leading cause of blindness worldwide, particularly among older adults, due to the clouding of the lens.

Glaucoma is an eye condition where the optic nerve is damaged, typically due to increased pressure within the eye, leading to loss of peripheral vision.

Sunglasses are primarily used to protect the eyes from harmful ultraviolet (UV) rays emitted by the sun, reducing the risk of eye damage.

Talking watches are assistive devices that announce the time and other information audibly, helping individuals with low vision to tell time independently.

Adults are recommended to consume approximately 5,000 IU of vitamin A daily to support good eye health and prevent vitamin A deficiency.

Macular degeneration is an eye condition where the macula, responsible for central vision, deteriorates, leading to loss of sharp central vision.

Eye drops are often used to treat eye infections, such as conjunctivitis, by delivering medication directly to the affected area.

Braille displays are assistive devices that convert digital text into Braille characters, enabling individuals with low vision to read and interact with electronic devices.
